Abstract
The growth of germ tube of Fusarium oxysporum f. sp. cucumerinum was remarkably inhibited on the water agar treated with 100ppm of Fe-EDDHA, a synthetic iron chelating agent, whereas germination rate of microconidia did not show much differences compare with that of non treated water agar. Both of the germination and the germ tube elongation of microconidia were suppressed significantly in King's B agar by the bacterial siderophores produced by Pseudomonas putida. The highest germination of the chlamydospores was obtained in the soil added with
오이덩굴쪼김병균 Fusarium oxysporum f. sp. cucumerinum의 소형분생포자는 물한천배지상에서 Fe-EDDHA를 처리하였을 때 시간이 경과됨에 따라 발아율이 증가되어 무처리와 유의차를 보이지 않았으나 발아관의 길이는 현저하게 짧았다. Pseudomonas putid의 Siderophore를 처리하였을 때는 포자의 발아율과군사신장이 모두 현저하게 억제되었다. 토양중에 형성된 후막포자가 발아하는데 필요한 영양물질로 Glucose; Peptone을 각각
